I made a flashbang prop! It has an optional springloaded retention arm. (For that to work you'll also need a Spring (mine was 7,5mm diameter, 35mm long and it's thickness was 0,7mm), a small locking pin (anything made of metal will work, I used a nail and snipped both ends off, it measures 1,5mm x 20mm) and you'll also need a keyring for the locking pin!

This is my first thing I've made that I thought worthy of uploading to Thingiverse! If you have any issues or questions, comment and I'll try to respond! If you enjoyed it and found it cool consider tipping!

(The parts are different colors because I ran out of filament and used white filament for the rest!)
